Grain deep processing integrated production technology for producing distilled liquor, rice vinegar and feed

The invention relates to a grain deep processing integrated production technology for producing a distilled liquor, a rice vinegar and a feed. The technology comprises the following steps: taking production raw materials according to a ratio of grains to water to distiller's yeast of 100 kg: (220-250) kg: 0.6 kg; crushing the grains, adding the crushed grains into water with a temperature of 25 DEG C, adding the distiller's yeast Zhengzhongchun into a closed fermenter with a stirrer, and fermenting and ripening the grains at 30 DEG C for 8-15 d; pumping the fermented and ripened raw materialsinto a solid-liquid separator through a pipeline and a residue slurry pump, and performing solid-liquid separation; conveying the obtained grain solid which is the dry residue high-protein feed into agranulator, and granulating the feed; conveying the obtained liquid into a distillation pot through a pipeline, and preparing the 50-55 DEG liquor from the liquid; recovering the liquor, continuouslydistilling the liquid to o
